Sagging floors, sinking girders and settling piers can result in unlevel floors, sticking or inoperable doors and windows and cracked drywall. 

Causes: 

• Floor framing spanned too far and sagged
• Floor framing weakened by rot and sagged
• Piers with improper footings that sunk
• Weight added to floor systems not designed to handle the load

First a hole is excavated for each SmartJack and a structural stone footing is compacted in place. Then the steel SmartJack is cut to size and installed under your sagging floor. The adjustable screw can jack up your floor, and can be easily adjusted again in the future.
